If you've found your diamond shoes are growing too tight and your wallet is too small to hold all your $50 bills, the Rolls-Royce Masterpiece London 2011 Drophead Coupe might be your answer. Why? It'll cost you both, and then some, most likely.

The height of Rolls-Royce opulence, the Masterpiece London Drophead Coupe is a one-off custom car, hand-built by the boffins and craftspeople at Goodwood. Built to "capture the essence of a perfect weekend get-away" in top-down style, it's home to a couple of features you won't find on any regular old Rolls.

A one-off Asprey jewelry box, for example, is mounted in the glove compartment, to hold the rings, cufflinks, and earrings you want to bring with you. It's also the first Rolls-Royce to get the Mazarine Blue exterior color, inspired by the butterfly of the same name.

Inside, it gets a leather interior in Seashell with Navy Blue contrast color, embroidered headrests, and yacht-inspired teak decking. Mother-of-pearl inlays highlight the Santos Palissander wood veneer and dash-mounted clock.

The car was built for the Masterpiece London 2011 show and will be on display at the Royal Hospital in Chelsea June 29-July 5.
